# Understanding P3

P3 (Unknown / 50-50) is one of the possible UMA resolution outcomes and is often a source of confusion. In controversial markets, participants sometimes push for P3 when there is no clear consensus, even when it is not the intended or appropriate resolution.

### When is P3 appropriate?

P3 is used when a market cannot be resolved objectively or verifiably under its rules. It is not meant to settle disagreements by giving both sides half. Mere controversy or disagreement is not enough to justify a P3 resolution.

Market-specific rules may also explain how particular edge cases should be handled. Some markets explicitly state that they cannot resolve to P3, while others provide instructions for ambiguous results, unavailable data, or other unusual circumstances. These rules take priority when determining the appropriate resolution.

If the resolution criteria are clear and verifiable, the market should generally resolve to either P1 or P2, even when participants disagree about the outcome.

### Common caveats

A poorly written market does not automatically justify a P3 resolution. Likewise, single-event, dead-on-arrival markets should generally still resolve based on whether the event occurred.

P3 should not be used before the deadline simply because the outcome remains uncertain, as the market may still resolve definitively.

When the community anticipates a P3 resolution, the market price may stabilize around 50¢ per share. This is not a guarantee of a P3 outcome, but it can signal growing expectations that no definitive resolution is possible under the market's rules.
